Abstract
PURPOSE: To facilitate the starting operation of vehicle on slope, by unlocking the parking brake when all of a circuit which operates when the rotational frequency of engine goes up to a predetermined level, a switch which operates when the clutch is partialy engaged, etc. operate simultaneously.
CONSTITUTION: When the rotational frequency of engine goes up and a rotation signal of high frequency is entered into an input terminal N, numerous pulses are transmitted at a constant period in a unit time from a transistor 17. When the rotational frequency of engine goes down, the number of the pulses from the transistor decreases. Another transistor 19 is turned on to energize a solenoid 21, only when the rotational frequency of engine is higher than a setpoint, a logic element 20 produces an output, the clutch is partially engaged, a switch 22 is open, the transmission is in lowest speed position or second lowest speed position and a switch 23 is open.
